I'm trying to set up an integration on Magento 2.4.4 but this is not working. The other side are reporting this error coming from Magento:
"Signature method HMAC-SHA1 is not supported"
Other integrations are working fine but I can't find any kind of logging on my end.
How can I debug this this to find out what the issue is?
From what I understand HMAC-SHA1 is supported by Magento https://devdocs.magento.com/guides/v2.4/get-started/authentication/gs-authentication-oauth.html
